Lethal Disseminated Mucorales Infection With Positive Blood Cultures With Purpura Fulminans Complicating Hemophagocytic Lymphohistiocytosis After Chimeric Antigen Receptor T-Cell Therapy.

We report a case of fulminant Mucorales fungemia in a heavily immunosuppressed cancer patient with hemophagocytic lymphohistiocytosis following CD70-targeted chimeric antigen receptor T-cell therapy. Although rare, Mucorales can cause true fungemia in a broad spectrum of hosts, with a range of manifestations from isolated fungemia to fungemia being part of widely disseminated, high-burden infection.

Concordance of Chest Radiography and Chest Computed Tomography Findings in Patients with Hematologic Malignancy and Invasive Mucormycosis: What Are the Prognostic Implications?

Invasive pulmonary mucormycosis (IPM) is a deadly opportunistic mold infection in patients with hematological malignancies (HM). Radiologic imaging is essential for its timely diagnosis. Here, we compared IPM lesions visualized by chest computed tomography (CCT) and chest X-ray (CXR) and determined the prognostic significance of discordant imaging.

Whole Blood Assay with Dual Co-Stimulation for Antigen-Specific Analysis of Host Immunity to Fungal and Viral Pathogens.

Rapid and resource-efficient sample processing, high throughput, and high robustness are critical for effective scientific and clinical application of advanced antigen-specific immunoassays. Traditionally, such immunoassays, especially antigen-specific T-cell analysis by flow cytometry or enzyme-linked immunosorbent spot assays, often rely on the isolation of peripheral blood mononuclear cells. This process is time-consuming, subject to many pre-analytic confounders, and requires large blood volumes.

Determinant of 30-Day Mortality of Pulmonary Legionellosis: Do Coinfections Matter?

We retrospectively reviewed 64 cases of cancer with pulmonary legionellosis ( in 73%). Nearly all patients received -active antibiotics, yet 30-day mortality was 23%. Independent predictors of 30-day mortality were hyponatremia, bilateral lung involvement, and Sequential Organ Failure Assessment score ≥5.
